A trading-window closure is a core control used by listed companies to stop designated persons from trading when they may possess unpublished price sensitive information, or UPSI. It is not the same as the broader insider-trading prohibition. Even when the window is open, Regulation 4 of the SEBI (Prohibition of Insider Trading) Regulations, 2015 separately prohibits an insider from trading while in possession of UPSI, subject to specified defences and exceptions.
SEBI's PIT Regulations page provides the official regulations route, while the consolidated PIT text hosted by SEBI contains the Schedule B rules on trading windows, pre-clearance and contra trades. SEBI's Comprehensive FAQs on the PIT Regulations add practical guidance on earlier pre-clearance, communication of closure and transaction treatment.
When must the trading window be closed?
Schedule B uses the trading window as a monitoring tool for designated persons. The compliance officer closes it when a designated person or class of designated persons can reasonably be expected to possess UPSI relating to the relevant securities. Designated persons and their immediate relatives must not trade in those securities while the window is closed.
For financial results, the rule is specific: the trading restriction period applies from the end of every quarter until 48 hours after declaration of the financial results. The current consolidated text also includes a 2025 proviso stating that for UPSI not emanating from within the listed company, the trading window may not be closed. That proviso does not remove Regulation 4's separate prohibition on an insider trading while in possession of UPSI.
Who is covered?
The company's code identifies designated persons based on role, function and access to UPSI, and Schedule B extends the closure restriction to their immediate relatives. The statutory concept of an insider is broader: a connected person, or anyone possessing or having access to UPSI, can fall within the insider-trading framework even if that person is not on the designated-person register.
Does earlier pre-clearance survive a later closure?
No. SEBI's FAQs say that a designated person cannot trade during a closed window merely because pre-clearance was granted while the window was open. The earlier pre-clearance becomes invalid once the window closes. The FAQs also say the compliance officer must communicate the closure; merely rejecting trades is not enough.
When an event-driven closure begins, compliance should therefore identify outstanding pre-clearances and treat them as unusable during the closure.
What happens when the window reopens?
The compliance officer determines reopening after considering whether the UPSI has become generally available and whether the market has had time to assimilate it. Schedule B says reopening cannot be earlier than 48 hours after the information becomes generally available.
An open window is only the first gate. If a proposed trade exceeds the pre-clearance threshold fixed by the board, the designated person must obtain pre-clearance under the company's code. The threshold is company-specific; Schedule B does not prescribe one universal rupee amount. The code must also specify a reasonable period for executing a pre-cleared trade, capped at seven trading days, after which fresh pre-clearance is needed.
Pre-clearance is not a safe harbour for UPSI
Before approving a trade, the compliance officer may seek a declaration that the applicant is not in possession of UPSI and must consider whether that declaration is reasonably capable of being inaccurate. SEBI's FAQs illustrate that a managing director may trade with pre-clearance if not in possession of UPSI, subject to the company's code. They also clarify that off-market transfers are trades for PIT purposes and may require pre-clearance under the code.
How is contra trade different?
Contra-trade control applies after a permitted trade and must be checked separately from the trading window. Schedule B requires the code to specify a period of not less than six months during which a designated person who has been permitted to trade cannot execute a contra trade. In practical terms, an opposite-direction trade within that restricted period can create a compliance issue.
The compliance officer may be empowered to relax the restriction for reasons recorded in writing, provided the relaxation does not violate the PIT Regulations. If a contra trade is executed in violation, the resulting profit is liable to disgorgement for remittance to SEBI's Investor Protection and Education Fund. The rule does not apply to trades pursuant to exercise of stock options, although transaction-specific ESOP sales should still be checked against the FAQs and the company's code.
Trading plans and specified exceptions
Trading-window norms do not apply to trades carried out under an approved trading plan. Current Regulation 5 requires at least 120 calendar days between public disclosure of the plan and commencement of trading under it, subject to the other plan conditions. Schedule B also identifies specified transactions for which window restrictions do not apply, but each exception should be tested against its exact regulatory conditions rather than treated as a blanket exemption.
The automated PAN-ISIN freeze
SEBI's current Master Circular on Surveillance of Securities Market, with the Master Circulars index as a fallback route, consolidates the framework for restricting trades of designated persons and their immediate relatives during financial-results closures. The framework uses PAN-level identification at the relevant security level and covers specified on-market transactions, off-market transfers and creation of pledges in equity shares and equity derivatives of the listed company.
The system control does not replace independent PIT compliance. Listed companies still need accurate designated-person and immediate-relative data, correct closure dates, timely updates and a defensible internal audit trail.
Worked example: quarterly results
Assume a listed company's quarter ends on 30 June and the board declares results on 25 July. For the financial-results restriction, the window is closed from the end of the quarter and cannot reopen until 48 hours after declaration, subject to the compliance officer's process and the company's code.
Suppose an employee received pre-clearance on 29 June for a sale but did not execute it before closure. That approval cannot be used during the closed window. After reopening, the employee must check whether the code's execution period has expired; if so, fresh pre-clearance is required. Compliance should also check prior opposite-direction trades because the six-month contra-trade rule is a separate control.
Practical trading-window checklist
- Maintain the population: keep designated-person and immediate-relative records and identifiers current.
- Calendar quarterly closures: map every quarter-end and results declaration.
- Review event-driven UPSI: assess promptly whether the relevant designated-person class can reasonably be expected to possess it.
- Communicate closure: notify affected persons and invalidate the practical use of outstanding pre-clearances.
- Reopen only after the conditions are met: ensure the required assimilation period has elapsed.
- Apply pre-clearance after reopening: use the board-approved threshold and code procedure.
- Check validity: ensure any pre-cleared trade is executed within the code's period, capped at seven trading days.
- Run the contra-trade lookback: test the minimum six-month restriction and document any permitted relaxation.
- Document exceptions: support trading-plan or other exemptions with the exact provision relied upon.
Common mistakes
- Treating an open window as proof that a person can trade while possessing UPSI.
- Assuming pre-clearance granted before closure remains usable during closure.
- Copying another company's pre-clearance threshold instead of following the approved code.
- Reopening immediately after disclosure without respecting the 48-hour minimum.
- Checking the window but forgetting the separate contra-trade restriction.
- Relying on the automated freeze while covered-person data is outdated.
Practical takeaway
A sound PIT process uses several gates: close the window when Schedule B requires it, communicate the restriction, treat old pre-clearances as invalid during closure, reopen only after the required period, apply the company's pre-clearance procedure and check the contra-trade lookback. The trading window is a monitoring mechanism; it never overrides the basic prohibition on trading while in possession of UPSI.
